问题:
在使用AVAudioPlayer调用play（或prepareToPlay）进行音频的播放（或预播放）时，竟然遭遇Crash。当时就一脸懵逼，这简单的调用都会出错！经过分析与资料查询，原来是我加了那种习惯性的异常断点（Exception Breakpoint）造成的。
对于这个问题，我在这里引用一下StackOverflow上的解答：
解答1：
Add your exception breakpoint and edit the exception type from "All" to "Objective-C exceptions"
Some classes in AudioToolbox throw regular C++ exceptions. You can filter them off this way.
解答2：
The problem was I normally develop with a breakpoint set to "All Exceptions", and the actual exception thrown was __cxa_throw.
Which apparently turns out to be in C++ libraries that are used to implement AVAudioPlayer.
By changing the breakpoint to "All Objective-C Exceptions" the program ran fine. (This can be done by editing the breakpoint and changing the Exception field to Objective-C.
总结：
总之，就是当两者相遇时，Exception Breakpoint你还是做出点改变吧，将你的类型由默认的“All”改为“Objective-C”。这不，他俩这会儿算是平静了，我也暂时轻松喽。
